I wouldn't know if it's anything really different.
Most Jaffa-Cake style cakes seem pretty much the same.
I know that McVitie's Jaffa Cakes (The original British one) are named after Jaffa Oranges from Jaffa, but I don't know if they do specifically use Jaffa Oranges in making them.
I would assume they do, but I wouldn't be sure.
I think generaly you're getting the same thing.
If it's in that style and it's an Orange flavour, then it's essentially a Jaffa-Cake.
And for those not in the know;
Jaffa Cakes!
